Description
The PI5A391A/392A/393A are monolithic analog switches de-
signed for low-voltage, single-supply operation. These high-preci-
sion devices are ideal for low-distortion audio, video, signal
switching and routing applications.
The PI5A391A is a quad single-pole single-throw (SPST), nor-
mally closed (NC) switch. The PI5A392A has four normally open
(NO) switches. The PI5A393A has two NC and two NO switches
per package.
Each switch conducts current equally well in either direction when
on. When off they block voltages up to the power-supply rails.
The PI5A391A/392A/393A are fully specified with +5V, and
+3.3V supplies. With +5V, they guarantee <12ohm on-resistance.
On-resistance matching between channels is within 2ohm.
On-resistance flatness is less than 4ohm over the full signal range.
The PI5A39X family guarantees fast switching speeds (t
ON
< 20ns).
These products are available in the 16-pin narrow-body SOIC,
QSOP, and PDIP packages for operation over the industrial (-40

to +85
